loose lenses on dslr

I have 3 manual lenses. Each one is a little loose on my *istDL I assume because of lack of electrical contacts. The 80-200mm is barely loose almost as tight as it ought to be. The 50mm is a little looser and the 135 is fairly loose. not enough to let light in but still loose.They all fit snug on my slrs .
My question is does anyone have an idea on a shim to snug the lenses up.that would last. I am only talking 1or 2 mm thick bout the thickness of the cardboard back to a note book or probably even thinner for the 135mm and about half that for the 50mm. I like using these but hate the wiggle they have on the DL
Thanks for any help

I use bits of inexpensive metal-duct tape on some lens bases to safely short the contacts to enable CIF. The tape is maybe 0.5mm thick; a couple layers should shim you out nicely. I bought a lifetime-supply roll of this tape at a not-cheap hardware store in a resort town for about four bucks; it ain't costly. Just be sure to get the shiny metal kind.

I have nothing useful to add. I just wanted to say how refreshing it is to see somebody who knows the difference between "loose" and "lose".

I've gotten so used to the ubiquitous error that at first I actually read your title as "Lose lens on DSLR".

I have yet to lose a lens on a SLR. An entire outfit, yes, but not just a lens. Whew.

If it may help, I made myself some shims from used soft drink cans (just remove the paint from the outside with some fine sand paper). On this Cunor, I have to use 2.

It's funny how things taught years ago in school tend to stick . This was drilled in as was the difference between to and too. The later ones I see often . Use to drive me nuts.
This looks like I may need to try making a couple of these tomorrow
